Carbon Steel National Standard Gate Valve

Ndife akatswiri opanga ma valve okhala ndi ziphaso za ISO, API ndi CE. Tili ndi zida zapamwamba zopangira ndikuwongolera mosamalitsa khalidwe lililonse. Timatenga maoda a OEM ndi ODM, ndipo MOQ yathu ndi yosinthika pama projekiti amitundu yonse. Mavavu athu amagulitsidwa kumsika padziko lonse lapansi, ndipo makasitomala nthawi zonse amaika maoda obwereza chifukwa cha khalidwe lathu lodalirika.

Kodi ma valve a gate nthawi zambiri amatsatira zotani?

Mavavu a pachipata amapangidwa mosiyanasiyana, kutengera komwe mudzawagwiritse ntchito komanso momwe mungawagwiritsire ntchito. Pama projekiti olemera a mafakitale ndi mafuta & gasi, API 600 ndiye muyeso wovomerezeka kwambiri. Imayang'anira mapangidwe a valve, zosankha zakuthupi ndi kuyesa kukakamiza. ISO 6002 ndi muyezo wina wapadziko lonse wofananira ndi API 600 wa mavavu a zipata zazitsulo za bonnet, pomwe timatsatiranso mulingo wa dziko la China wa GB/T 12234. Miyezo yonseyi imatanthawuza kukula, ntchito ndi zofunikira za chitetezo, kutsimikizira kukhazikitsidwa koyenera ndi kugwira ntchito mokhazikika kwa nthawi yayitali.

Makhalidwe Ofunika

Kodi mungafotokoze zomwe muyezo wa API 600 umaphimba?

API 600 ndi muyezo wamakampani wotulutsidwa ndi American Petroleum Institute. Amagwiritsidwa ntchito kwambiri pazipata zachitsulo za bonnet, zomwe zimagwiritsidwa ntchito kwambiri poyenga, mapaipi amafuta & gasi ndi zovuta zina zogwirira ntchito. Mulingo uwu umayang'anira kusankha kwazinthu, kapangidwe kake, njira zopangira komanso kuyeserera kosiyanasiyana & kulimba. Zimatsimikizira kuti valavu iliyonse imatha kupirira kupanikizika kwakukulu, kutentha kwakukulu ndi zofalitsa zovuta pakugwira ntchito kumunda. Ngati valve yachipata ikumana ndi API 600, imamangidwa kuti ikhale yokhazikika, yofunikira.

Kodi WCB ndi zinthu zotani zamatupi a valve?

WCB ndi gulu lodziwika bwino lopangidwa ndi zitsulo za kaboni pansi pa ASTM A216, lalifupi la "Weldable Grade B Cast Carbon Steel." Ichi ndi chimodzi mwazosankha zodziwika bwino zamatupi a valve chifukwa zimalinganiza mphamvu, kuwotcherera komanso mtengo wake. WCB imagwira ntchito m'mafakitale ambiri, kuphatikiza madzi, mafuta, gasi ndi mizere ya nthunzi, ndipo imayendetsa kutentha kuchokera -29°C mpaka pafupifupi 425°C. Ndi yolimba, yosavuta kuyika m'mawonekedwe ovuta, ndipo imagwira ntchito ndi mitundu yosiyanasiyana ya kukakamiza.

Ndi mtundu wanji wa valve wa pachipata womwe umagwiritsidwa ntchito kwambiri pamakampani?

Valve yachipata cha wedge ndiye mtundu wodziwika kwambiri pamapaipi amakampani. Ili ndi chimbale chooneka ngati mphero chomwe chimatsetsereka pakati pa mipando iwiri kuti chitsegule kapena kutseka kutuluka, ndikupanga chisindikizo cholimba chikatsekedwa kwathunthu. Mapangidwe ake ndi osavuta komanso odalirika, ndipo amagwira ntchito bwino pazovuta zambiri komanso kutentha. Mudzawapeza m'malo opangira madzi, malo opangira magetsi, malo opangira mafuta ndi gasi, ndi malo opangira mankhwala - ndizomwe zimapangidwira ntchito zambiri zowongolera.
